Cold Fusion Back In The Limelight - Guest Speaker Dr. Brian Josephson

In summary, there is a discussion on the Physics Forums regarding a supposed breakthrough in cold fusion by Italian scientists. However, there is a lack of evidence and credibility for their claims, and they have not been published in a legitimate scientific journal. Despite some initial peer-review, the scientific community is skeptical and waiting for more concrete proof before considering this a valid discovery. If this breakthrough were genuine, it would have already made major headlines.

It is agreed that theoretically Rossi, Levi, and Forcadi could all be in some deception together, but what would be the point? I gather Rossi's preference was to keep quiet until the 1MW reactor had been completed, but Forcadi leaked the news to the local press.

I've been discussing with Jed Rothwell the issue of Rossi saying 'if the 1MW reactor is completed in October' or words to that effect. He comments that scaling the process up by combining 100 reactors into 1 unit might encounter unanticipated problems that it would take time to resolve, hence the tentative nature of the statement.
How much excess heat? Even if the temperatures and flow rate presented by Levi are accepted, they provide clear evidence of only about 1.8 kW power out, with 1 kW electrical power in (the average reported by Levi). That leaves only about 800 W for 40 minutes to be accounted for, which is certainly not enough to rule out chemical sources, given the size and weight of the device, not to mention the connection to a 13 kg bottle of hydrogen.
Check your figures!

There has been discussion of this paper in the condensed matter nuclear reactions (CMNS) discussion group. The conclusion is that if the catalyst acts selectively on the isotopes of Ni the apparent discrepancy can be resolved, though uncertainties remain.

If Rossi wanted instant credibility

Who said Rossi wanted instant credibility? Perhaps he wants something more noble, like to do something great for mankind. Perhaps he wants to get rich. If one is convinced that one's technology works, then time will out, credibility will arrive.

What you are asking for instant satisfaction for your curiosity - which Rossi is not duty bound to provide. If you want a satisfying demonstration, then why not try it yourself? It seems like this may be the only way you could be satisfied that there are no 'tricks'

@bjosephson: I believe that your post #64 indicates that you are actually going to make an attempt to replicate this effect. I think this is the true reponse of a scientist to the situation that presents itself. With the rewards being so high, this possibly being the most important challenge that has ever presented itself to the scientific community, i.e. how to solve the world energy crisis before half the world starves or freezes, then anyone with the resources to do so should be attempting to replicate, then extend the development of, this potential break through.

I have failed to convince my Unversity Dept to also make an attempt to replicate the effect. They do appear to have a valid reason in that we do not have the necessary resources.

As for all those in the "let's sit on the fence and not risk our reputation" camp, then shame on you. Where I have great respect for the scientific method (including peer reviewed journals), we should remember what came first, science or peer reviewed journals? Most of the great, paradigm changing scientific discoveries had to battle with the establishment before they were accepted. This is following exactly the same pattern, I think history will prove this to be so.

Dr Josephson's arguments (that the effect is real and cannot be explained by chemical reactions) in this thread are comphrensive. I did not need convincing, as I have been following the Rossi story for many months, however if you still do, then I suggest you read post 41 and attempt to counter the science.

Prehaps the deniers amongst you should consider why you are so resistent, possibly there is some subconscious reaction... think who are the big losers if this break through is allowed to develop - mainly the oil giants, who probably control PR companies, who possibly control your mind (to some degree).

I notice that the web page in question does not consider the 1.4% Ni-61 nor the 3.6% Ni-62 of naturally occurring Ni as candidate reactants to Ni+H-->NN-XX + energy. Why these were discounted is not clarified.

Oh, please ... can you really not see any possible ways they could make personal financial gains from this sort of deception?

Not that I am accusing either them or you of either dishonesty or naivety. I have no evidence either way. But I don't assume that because I don't have any hard evidence somebody is a sinner, then it follows they must be a saint.

I have no idea. They may be sincere and mistaken, or sincere and right, or they may be individually deceptive for different reasons or collectively deceptive for the same reasons.

But I am reluctant to accept a revolutionary discovery based on my failure to understand their motivation. If they can meet ordinary standards of independent verification, they deserve an audience. Otherwise, I remain skeptical.

Check your figures!

Which figures are you questioning? A flow rate of 4.9 g/s water, and a temperature increase of 88 degreesC corresponds to 1.8 kW. Evidence for conversion of more than a percent or so to steam was not presented. The 1 kW average input power was quoted by Levi.

Newton's laws were immediately accepted, as was Einstein's relativity, at least on the scale of a few years. Quantum mechanics ideas and theories were devoured as quickly as people could put them forward; de Broglie's matter waves won him a Nobel prize a mere 6 years after he proposed them. Apart from debates about philosophical implications, the methods and predictions of quantum mechanics met with very little serious opposition. High temperature superconductivity was immediately accepted, even in the absence of a theory to explain it.

You are probably thinking of Galileo and Darwin, but objections to their ideas were religious, not scientific.

Cold fusion itself provides a contradiction to your statement. When it was announced in 1989, and people had no reason to be skeptical, Pons & Fleischmann, like Einstein before them, became international celebrities. Physics and chemistry labs all over the world suspended their current research, and started doing electrolysis with Pd and D2O. Everyone wanted in on the revolution. Everyone was trying to get their slice of the glory that was sure to follow. The ACS meeting that followed shortly after was packed with scientists mocking the high-energy physicists who had apparently been pwned by two humble chemists. Everyone was giddy with anticipation of free and clean energy. Everyone, including me, was open to the idea and wanted it to be true. The subsequent skepticism can therefore not be attributed to resistance to new ideas.

Post 41 does not address the most important objection to Rossi's claims, that they have not been subject to independent verification. The post merely accepts the data obtained in a private experiment as claimed by Rossi and Levi. If we're prepared to accept whatever Rossi and Levi say, without verification, then what's the point of examining their data; we can just accept their claim that they have produced a radiationless, 15 kW H-Ni fusion reactor, and get in line to buy one.

It seems rather pointless to argue about the details of an experiment no one else is in a position to perform, or even observe.

Would you like to approach Rossi about getting one of his proprietary reactors to me for testing? I have a hunch he's not prepared to supply one.

You claim that the events in January were not public or a demonstration. Why does it matter if this one is claimed to be a public demonstration or not?

Which of your claims was not addressed in the second demonstration. The only claim that can be made against the validity of the second result is fraud. There is no possibility of experimental error that large.

Since the same experimenters performed both "demonstrations" if the explanation for the second result is fraud, the first one must be fraud as well.

The claim of fraud is weak.

Why would someone, having learned from experience, announce an even more incredible cold fusion result in a press conference in almost the same fashion as Pons and Fleischmann? Certainly not to gain credibility. That is absurd.

Do you think there is a single con man in the world that would try to pass off a cold fusion breakthrough fraud scheme in this fashion. Why choose cold fusion which is universally reviled by the very lay-people a con man would target?

Have you considered another alternative?

Perhaps the inventors of this device, who have toiled for 2 decades under in obscurity, ostracized by their peers, are deliberately introducing their work in this way so that all the self interested detritus of the scientific community can be drawn into pile their derision on the phenomenon. Then when a more complete set of observations are presented, the ignorance, lazyness, and corruption that allowed cold fusion to be falsely relegated to the status of "junk science" will be revealed.

Are you prepared to stand up and proclaim your faults should this device be genuine? I, for one, intend to crow about my gullibility and foolishness should a fraud be revealed (though it will not shake my belief in cold fusion, for which much more credible evidence already exists).

4) if a flaw were discovered in the way the excess heat is measured, that would be evidence against the claim. If you can't find a flaw then the claim stands.

Dr. Josephson, following the debates on some Italian forums on the this subject I picked up 3 major incongruities among what is stated in the Dr. Levi’s calorimetric report on the January 14th test and what can be seen in others documents available on the web, such as photos and movies.

Being the images more meaningful than words, I prepared the attached pictures that explains these 3 apparent incongruities:

1 - HP474AC probe mentioned in the calorimetric report does not correspond to the probe used during the test (please see attached probe.jpg). This would heavily affect the sentence regarding the dry condition of the steam;

2 - Dosimetric pump is very similar to LMI J5 pump whose maximum flow is only 40% of the water flow written in the calorimetric report (pump.jpg). This is the same comment raised by Joshua Cude;

3 - In calorimetric report, a duration of 40 min for boiling condition is assumed, but it lasted only the half (duration.jpg).

What do you think about these incongruities? Are they solid flaws that can justify some doubts about the conclusions claimed in the report?

Thanks

Einstein was heavy persecuted by the Nazis his work called "Jewish trash" and public burnings of his books, doesn't sound like acceptance to me.

I wonder why (some) people are putting so much effort into criticising the preliminary investigation, which all agree was imperfect, and ignoring the second, which dealt with these criticisms?
